Hi all, I just upgraded my hardware and I have RAID 1 set up and working on the first 2 partitions after swap of both my hard drives.It boots ok into the first RAID partition, /dev/md0, with openSUSE12.1. However, I am now unable to get my backup partition started on /dev/md2, where I have openSUSE 11.4 installed. When I try and boot into /dev/md2, my system gets past grub, but then as it is booting up, udev sets up device /dev/md126 on 2 drives (I don't know which RAID this is or where it gets the number 126), and then it cannot find the root drive. (It does not do that when I boot into /dev/md0, where I have openSUSE 12.1 installed.) When I select the 3rd option I set up on grub, to boot into openSUSE 11.4 on my degraded RAID, this is what shows up on the boot sequence: doing fast boot Creating device nodes with udev mdadm: /dev/md126 has been started with 2 drives. Trying manual resume from /dev/disk/by-label/swap2 Invoking userspace resume from /dev/disk/by-label/swap2 resume: libgcrypt version 1.4.6 Trying manual resume from /dev/disk/by-label/swap2 Invoking in-kernel resume from /dev/disk/by-label/swap2 Waiting for device /dev/disk/by-label/AltOldLinuxRoot to appear: .^[................................ Could not find /dev/disk/by-label/AltOldLinuxRoot. Want me to fall back to /dev/disk/by-label/root? (Y/n) So it never finds the RAID partition to boot into it, even though grub found it no problem (I had to set up the degraded RAID specifying metadata 1.0, because when I tried it with the default 1.2, the superblock is stored 4k from the start, so grub couldn't find the boot directory). Ok, here is some background. My partitions are set up as follows: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes Device Boot Blocks Id System LABEL /dev/sda1 2095104 82 Linux swap / Solaris swap2 /dev/sda2 * 20973568 fd Linux raid autodetect linux-aw90:0 /dev/sda3 465306624 fd Linux raid autodetect linux-aw90:1 /dev/sda4 488385536 f W95 Ext'd (LBA) /dev/sda5 20971520 83 Linux root2 /dev/sda6 20971520 83 Linux /dev/sda7 446429184 83 Linux xtradata Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes Device Boot Blocks Id System LABEL /dev/sdb1 2095104 82 Linux swap / Solaris swap1 /dev/sdb2 20973568 fd Linux raid autodetect linux-aw90:0 /dev/sdb3 465306624 fd Linux raid autodetect linux-aw90:1 /dev/sdb4 488385536 5 Extended /dev/sdb5 20971520 fd Linux raid autodetect linux-aw90:2 /dev/sdb6 20971520 83 Linux roottemp /dev/sdb7 446429184 83 Linux newkde These are my RAID1 partitions Device Device RAID device LABEL /dev/sda2 /dev/sdb2 /dev/md0 root /dev/sda3 /dev/sdb3 /dev/md1 home /dev/sdb5 missing /dev/md2 AltOldLinuxRoot I have no problem being able to boot into /dev/md0, as this is my normal OS. What I am trying to do is also be able to boot into /dev/md2 while it is still a degraded RAID. Grub reads my menu.lst file just fine. This is the 3rd option I have setup in menu.lst, and I have copied just that section here: ###George's option on /dev/md2### title extended partition openSUSE 11.4 on /dev/md2 kernel (hd1,4)/boot/vmlinuz-2.6.37.6-0.9-desktop root=/dev/disk/by-label/AltOldLinuxRoot resume=/dev/disk/by-label/swap2 splash=silent quiet showopts vga=0x317 initrd (hd1,4)/boot/initrd-2.6.37.6-0.9-desktop Here is what my /etc/mdadm.conf looks like on the openSUSE 11.4 partition DEVICE containers partitions ARRAY /dev/md0 UUID=e96a14ed:bc7c8d5a:9b0c114a:9e208631 name=linux-aw90:0 ARRAY /dev/md1 UUID=cdfe9dc0:73d6f7cb:7dda2c20:e3758f4f name=linux-aw90:1 ARRAY /dev/md2 UUID=9e211746:31896532:b4f86782:184e93f7 name=linux-aw90:2 So, any help getting my system to boot in my 11.4 degraded RAID partition? -- G.O.
